Installation pricing flagged as high by 5 reviews — $2,330 install on a $1,600 water heater; $300+ quote became $500 mid-job for 'back-to-back sinks'
“The installation service by Johnny and Aiden was outstanding. Very professional and detailed workmanship. Cost for this great service seems high though. $2330 plus an additional $300 for a part seems a lot for installing this high performance platinum hybrid heat pump/water heater.”

I was later told by the 535 dispatche that the lead tech was a personal friend of the …”
Positive
“I don’t normally take the time to write reviews, but 535 Plumbing LLC absolutely deserves to be recognized. We noticed water leaking from under our stove in the kitchen, and there was obvious water damage starting to show. From the very first call, their customer service — especially Maurice — was professional, responsive, and straightforward. No runaround, no upselling, just clear communication and honest …”
“535 Plumbing is highly recommended for same day plumbing emergencies. Aren't most plumbing issues "emergencies" needing same day attention?
